<span>y = 3x + 1 because if you put it on a graph it is the one that comes out straight so therefore it is a linear function.</span>
Red=20 (1/3 x 60=20)
Blue=30 (1/2 x 60=30)
Green=5 (1/12 x 60=5)
White=5 (1x12 x 60=5)
If you're asking for the measurements, they are...
Length (l) = 4 ft.
Width (w) = 4 ft.
Height (h) = 4 ft.
First subtract four from both sides and get n/2=-8. Then multiply both sides by 2 and get n=-16
Answer:
10.61 cm
Step-by-step explanation:
From the question,
The volume of the rectangular piece of metal = Volume of the 45 cylindrical plates.
Volume of a cuboid = 45×volume of a cylinder
lwh = 45×πr²h..................... Equation 1
Where l = length of the rectangular piece of metal, w = width of the rectangular piece of metal, h = height of the rectangular piece of metal, r = radius of the cylindrical plates, h = thickness of the cylindrical plates.
make h the subject of the equation
h = lwh/(45πr²).................... Equation 2
Given: l = 12 cm, w = 18 cm, h = 10 cm. r = 1.2 cm
Constant: π = 3.142.
Substitute these values into equation 2
h = (12×18×10)/(45×3.142×1.2²)
h = 2160/203.60
h = 10.61 cm.
